This PR adds the options to customize what information is shown in long format regarding author, group & owner. Specifically it adds:
- `--author`: shows the author, which is always the same as the owner. GNU has this feature because GNU/Hurd supports a difference between author and owner, but I don't think Rust supports GNU/Hurd, so I just used the owner.
- `-G` & `--no-group`: hide the group information.
- `-o`: hide the group and use long format (equivalent to `-lG`).
- `-g`: hide the owner and use long format.
The `-o` and `-g` options have some interesting behaviour that I had to account for. Some examples:
- `-og` hides both group and owner.
- `-ol` still hides the group. Same behaviour with variations such as `-o --format=long`, `-gl`, `-g --format=long` and `-ogl`.
- They even retain some information when overridden by another format: `-oCl` (or `-o --format=vertical --format=long`) still hides the group.
My previous solution for handling the behaviour where `-l1` shows the long format did not fit with these additions, so I had to rewrite that as well.
The tests only cover the how many names (author, group and owner) are present in the output, so it can't distinguish between, for example, author & group and group & owner.

This little check, allows us to hide the files that
shouldn't be shown on the listing on Windows operating
systems.
Just like the "dot" in UNIX based operating systems
Windows uses its own file attributes to determine if a file
is hidden or not.
The lack of support for this option is normally an annoyance
for many users, this commit adds full support for this feature
